Name: A.2549
Reference: EcoArt 2002
Description: The ~~Artemisia arbuscula ssp. longiloba$ Shrubland Alliance (A.2549)$$ occurs in Nevada, but is likely fairly widespread in the Intermountain West, the southern Rocky Mountains and in the western Great Plains. Stands are found on a variety of landforms; from flats and depressions to alluvial fans and hillslopes and ridges. Soils are generally characterized by a heavy clay subsoil occurring within 25 cm of the soil surface, which restricts rooting depth. Soils are also alkali and calcareous. Little information is available on vegetation included in this alliance except that it is dominated by a low-shrub layer of ~Artemisia arbuscula ssp. longiloba$. Shrub associates are not specified, but presumably include ~Artemisia tridentata, Artemisia tripartita, Chrysothamnus viscidiflorus, Gutierrezia sarothrae$, and ~Purshia tridentata$. The herbaceous layer is generally sparse. Various perennial graminoids may be present, but with low cover (<20% cover). Important grasses include ~Festuca idahoensis, Pseudoroegneria spicata, Elymus elymoides$, and ~Poa secunda$. Forb cover is likely sparse. Diagnostic of this alliance is the ~Artemisia arbuscula ssp. longiloba$-dominated low-shrub layer (or codominated with >40% relative shrub cover of the nominal species) and lacks a significant graminoid layer (<20% cover perennial graminoids) or has over 40% total shrub cover.
